•
Multiple starts or cold operation
•
Incorrect maintenance intervals
•

Incorrect oil
•
Contaminated oil
•
Leaks in air intake system
•
Dirt in fuel

Low oil pressure
Recommended Actions
Multiple Starts or Cold Operation
Frequent starting and stopping of the engine can
cause early wear. Also, operation of the engine for
short periods of time in cold conditions can cause
early wear.
Incorrect Maintenance Intervals
If the engine is not correctly maintained, early wear
will occur.
Make sure that the engine is maintained at the
correct maintenance intervals. Refer to the Operation
and Maintenance Manual, "Maintenance Interval
Schedule".
Dirt in Engine Oil
1. Drain the oil from the crankcase and refill the
crankcase with clean engine oil. Install new engine
oil filters. Refer to the Operation and Maintenance
Manual for more information.
Incorrect Oil
1. Check that the engine is filled with oil of the
correct specification. Refer to the Operation
and Maintenance Manual, "Refill Capacities and
Recommendations".

2. If necessary, drain the engine oil system and
refill the engine oil system. Refer to Operation
and Maintenance Manual, "Engine Oil and Filter
- Change".
Contaminated Oil
Check an oil sample for contamination with fuel. If
contamination is found, investigate the cause.
Leaks in Air Intake System
A leak in the air intake system may allow unfiltered
air into the engine. Inspect the air intake system for
streaks which may indicate a leakage of unfiltered
air. Inspect all of the gaskets and the connections.
Repair any leaks. Refer to Testing and Adjusting, "Air
Intake System" for more information.
Dirt in Fuel
1. Remove the fuel filters. Inspect the fuel filters
for contamination. Install new fuel filters. Refer
to the Operation and Maintenance Manual, "Fuel
System Filter- Replace" and Operation and
Maintenance Manual, "Fuel System Primary Filter
(Water Separator) Element - Replace". Determine
the cause of the contamination.
2. Check the diesel fuel for contamination. Refer to
Testing and Adjusting, "Fuel Quality - Test".
Low Oil Pressure
Refer to Troubleshooting, "Low Engine Oil Pressure"
for the testing procedure. Repair any identified faults.
